Watts U5B Valve Set

Description:

The Watts U5B 2" Valve Set (Standard Range: 25–75 PSI) is a water pressure reducing valve designed to regulate incoming water pressure and protect plumbing and process systems from excessive pressure. Commonly installed in commercial buildings, industrial facilities, and municipal water distribution systems, it helps maintain stable downstream pressure while reducing water consumption and system wear. Maintenance teams, plumbing contractors, and system integrators use the Watts U5B 2" Valve Set for replacement, retrofit, and new installations requiring reliable pressure regulation.

Applications:

The Watts U5B 2" Valve Set is commonly used in commercial plumbing systems, industrial process water lines, manufacturing facilities, irrigation systems, multi-story buildings, and municipal water supply networks. The Watts U5B 2" is engineered to reduce and stabilize water pressure in applications where a standard adjustable range of 25–75 PSI is required to protect downstream equipment and plumbing components.
